Apartment heat advice

I live in a pre-war building (second floor, not too high up) and I have a radiator in my bedroom, living room and kitchen. I can’t control the heat in my bedroom unfortunately and it’s always SO hot in the winter, like 84 degrees. It’s unlivable, but I’ve researched that you shouldn’t complain to your landlord because they’ll just shut off the heat. Is there anything else I can do to cool down the room besides suffer? I usually have my windows open in the winter but on rainy days I can’t do that lol
